I've got an RV-8 and there just isn't a certified analog to it:
cruise at 160 knots on 6.5-7 gph
Operate out of 1000 foot grass strips with impunity(rougher than you'd think but not super cub rough)
800-1000 mile range
Run auto spark plugs that cost $20 for a full set rather than $20 each
Electronic ignition for easy starting, and TBO well beyond MAG TBO
Avionics that blow away the certified competition
Annuals that cost peanuts
However... I did build mine and I've been careful about what goes into the plane especially the electrical system. I've been very lucky and only had a few
issues.
Used homebuilts are a mixed bag... in general people don't sell well built, good running airplanes...
I've had a number of friends who have been burnt with unexpected issues buying experimentals. Some of them very experienced and knowledgeable.
